Current Regulation - Diodes, Transistors Procurement Notes

Verify that the ordering suffix UR-1 corresponds specifically to the tape-and-reel packaging format required for automated assembly processes. Confirm that the JAN prefix indicates compliance with the full MIL-PRF-19500/463 qualification requirements rather than commercial equivalents. Ensure that the specified temperature range and voltage ratings align with the system's operational constraints before finalizing procurement orders.

Current Regulation - Diodes, Transistors Selection Notes

Select this component when a fixed current source is required in a compact surface-mount form factor. The DO-213AB package is suitable for space-constrained PCB layouts. Consider the 3.96 mA output value against circuit requirements; if different current levels are needed, review adjacent part numbers in the 1N531x series. Verify that the 100 V breakdown voltage exceeds the maximum potential difference across the diode in the intended application.

Current Regulation - Diodes, Transistors Part Context

This part belongs to the JAN series of current regulator diodes produced by Microchip Technology. It shares functional similarities with other devices in the 1N531x family but is distinguished by its specific current rating and military-grade qualification. The UR-1 suffix typically denotes the reel packaging variant, differentiating it from bulk-packaged counterparts like the JANTX1N5311UR-1.
